CodeHealth MCP

The Problem

Dead code, circular dependencies, excessive coupling, and architectural drift are invisible in day-to-day work. Static analysis tools produce noise in CI dashboards nobody checks. CodeHealth MCP brings these insights into the tools developers actually use — via the Model Context Protocol.

What CodeHealth MCP Does

6 analysis tools, available in any MCP-compatible client:

Where It Works

Claude Desktop Config

{
  "mcpServers": {
    "codehealth": {
      "command": "node",
      "args": ["/path/to/codehealth-mcp/mcp-server/index.js"]
    }
  }
}

Quick Start

git clone https://github.com/icohangar-ops/codehealth-mcp.git
cd codehealth-mcp
npm install
cp .env.sample .env
# Edit .env with your LLM API key
npm start

Use in Claude Desktop

Run a full health scan on /path/to/my/repo

Find circular dependencies in the frontend

Check coupling metrics in src/services

Daytona sandbox scans (optional)

Set DAYTONA_API_KEY (and optionally GITHUB_TOKEN for private repos). MCP tools and Slack analysis will shallow-clone GitHub URLs in a Daytona VM and return live import-graph findings instead of demo data.

full_health_scan repo_path=https://github.com/org/repo

Use in Slack

Add the Slack app manifest, enable Agent Builder, and @CodeHealth in any channel.

Slack Integration

CodeHealth MCP ships with a full Slack Agent Builder app featuring:

• Block Kit UI — Severity-coded findings, health scores, actionable suggestions
• Thread-based conversations — Follow-up analysis in threads
• Suggested prompts — One-click analysis triggers
• MCP server — Same tools, available everywhere

Demo Sandbox (Devpost judges)

The live demo workspace is codehealthdemo.slack.com — the CodeSentinel agent (App ID A0BEHRDN5TQ) is installed and authorized there. Mention it in any channel:

@CodeSentinel run a full health scan on https://github.com/icohangar-ops/codesentinel

Sandbox configuration:

Live agent response in the sandbox — a real @CodeSentinel mention in #general triggering a Daytona-sandboxed repo scan:

App credentials & App ID	Agent capability enabled	Socket Mode enabled

Adding Custom Analyzers

Each analyzer follows a simple interface:

function analyze(repoInfo) {
  return {
    type: "your_analysis_type",
    findings: [
      {
        type: "finding_type",
        severity: "critical" | "warning" | "info",
        file: "path/to/file.ts",
        line: 42,
        name: "symbol_name",
        reason: "Why this is a problem",
        suggestion: "How to fix it",
      },
    ],
    stats: { /* summary metrics */ },
  };
}

Add a new analyzer in lib/analyzers/, register it in analysis-engine.js, and it's automatically available in Slack and via MCP.

Roadmap

• Real AST analysis — ts-morph for TypeScript, tree-sitter for multi-language
• GitHub App — Automatic analysis on PRs with inline comments
• Historical trends — Track health score over time per repo
• Custom architecture rules — Define layer boundaries via config
• Team dashboards — Aggregate health in Slack Canvas
